PURPOSE: We evaluated radiologic and clinical outcomes to compare the efficacy of anterior cervical discectomy and fusion (ACDF) and anterior corpectomy and fusion (ACCF) for multilevel cervical spondylotic myelopathy (CSM). METHODS: A total of 40 patients who underwent ACDF or ACCF for multilevel CSM were divided into two groups. Group A (nÃ?Â =Ã?Â 25) underwent ACDF and group B (nÃ?Â =Ã?Â 15) ACCF. Clinical outcomes (JOA and VAS scores), perioperative parameters (length of hospital stay, blood loss, operation time), radiological parameters (fusion rate, segmental height, cervical lordosis), and complications were compared. RESULTS: Both group A and group B demonstrated significant increases in JOA scores and significant decreases in VAS. Patients who underwent ACDF experienced significantly shorter hospital stays (pÃ?Â =Ã?Â 0.031), less blood loss (pÃ?Â =Ã?Â 0.001), and shorter operation times (pÃ?Â =Ã?Â 0.024). Both groups showed significant increases in postoperative cervical lordosis and achieved satisfactory fusion rates (88.0 and 93.3Ã?Â %, respectively). There were no significant differences in the incidence of complications among the groups. CONCLUSIONS: Both ACDF and ACCF provide satisfactory clinical outcomes and fusion rates for multilevel CSM. However, multilevel ACDF is associated with better radiologic parameters, shorter hospital stays, less blood loss, and shorter operative times.
